According to MSDN, If DCX_CACHE is not specified and the window is neither CS_OWNDC nor CS_CLASSDC, this function returns NULL.. Have you use Spy++ to look at the window properties?
BTW, thanks for formatting your code with PRE - makes it a lot easier to read.
Best wishes,

Hi,
Is there any API/MFC to remove temporary internet files.
Warm Regards,

You can use GetSpecialFolder(/*parameter*/) and then delete all the files in the temp folder using DeleteFile(/*parameter*/).
Somethings seem HARD to do, until we know how to do them.

Hello 
I well understand the mechanism of Double Buffering and find a lot of samples, where text or lines were
drawn over the CDC *pDC, which i also understand.
But is it possible to draw textboxes over a CDC *pDC?
Because in my OnSize function i resize the groupboxes and slide all textboxes via MoveWindow.
I could use a MoveWindow without redrawing an set an Invalidate or Redraw if the view to redraw the entire view with the changings.
But i also need to redraw the groupboxes, so they begin to flicker during moving.
Is it possible to redraw a textbox into a OnDraw(CDC *pDC) Handler?
Thanks for answers

Do you want to customize EditBox?

No, i like to draw all components to a ScreenBuffer (textboxes,groupboxes,CStatics,...) then, after
redrawing all controls, the screen should draw one time the ScreenBuffer.
The ScreenBuffer is a copy of the CDC *pDC and lines,texts are drawn into the buffer.
But how to draw a textbox into the buffer 
Thanks for your answer

Hi,
While debugging in VC++, I wish to goto the previous statement? Is it possible ? if so can you please explain. For example if my cursor is at statement 10 and i want to move to statement 9.
Thanks in advance.

Just click on the cursor at the current position and drag it to the statement from which you want to continue.

HI All,
I have to download a file(in binary format) from a remote server.
The problem: The problem is that the firewall will see an HTTP connection and in that stream it will look at the headers and find that it is binary (Content-type: application/octet-stream). This will cause it to assemble the stream on the firewall and inspect it thus stripping the attachments that are in binary form.
Any ideas on how can this be achieved?

I want to check in my VC++ code if a file is blocked. Normally when exe files are transferred over email, they will be blocked.If you go to the property of the file, you will see "Security: This file came from another computer and might be blocked to help protect this computer" and there will be a button to unblock it. I have to programmatically check this case. Is there any API or function that could help me get this information.
Thanks in advance.

Hi,
does the TabStop property to TRUE resolves your problem.
Or, without the Ressouce-Manager via ModifyStyle(0,WS_TABSTOP);
Good luck

Hi all,
I have developed an application as an installation in VC++. I am using Visual Studio 2005. I have used Launch Condition Editor for checking whether .NetFramework has been installed or not. If it is installed only, the installation should take place. But, when I am trying to install in a system having .NetFramework also, the installation doesn't work. It returns that the .NetFramework is not installed.
I have referred this link for implementing the check : Support From Microsoft[^]
Can anybody please help me....
Thanks in Advance...

If you can't get it to work that way, you could always use this technique.
BTW, your link doesn't work.

This is a very general question, and you probably won't get much help with it. You need to specify 1) what kind of errors you're talking about (app crash, api failure, compile error?); 2) what kind of handling (e.g., do you want to catch it in the debugger, log it to a file. display a message box?); and 3) when you want to handle the error (during development/debug, when using the app, etc.).
If you are talking about a specific error, then you should include the error text in your post, giving details.
Finally, please note that most of the people here would like very much to help you, so it would be nice to show them some courtesy by taking the time to write out "please" instead of "pls". If you don't have the time to do this, then why should anyone take the time to help you?
Best wishes,
Hans
